Description

The DC Master 24/12-12 Isolated is a DC-DC converter that delivers a stable 13.6 V output from a 24 V battery system, supplying up to 12 A continuously to onboard 12 V equipment. It is intended for recreational and semi-professional installations where some equipment runs at 24 V while the rest of the system needs a reliable 12 V supply.

As an isolated model it provides full galvanic isolation between the input and output circuits. This makes it extra touch-proof and suppresses interference for sensitive equipment, and it can be used with negative or positive grounding. The converter also provides two minutes of extra capacity, delivering up to 18 A for short intervals when a brief power boost is needed.

The unit is stabilised, naturally cooled and rated to IP53. It carries CE and E-mark compliance and is delivered complete with a mounting bracket, screws and fasteners for quick installation.

What does isolated mean on this converter?
It means there is full galvanic isolation between the 24 V input and the 12 V output, with no direct electrical connection between them. This makes the unit extra touch-proof, suppresses interference for sensitive equipment, and allows use with either negative or positive grounding.
How is it different from the non-isolated 24/12-12?
Both deliver 12 A continuously at 13.6 V from a 24 V system, but the isolated model adds galvanic isolation between input and output and carries CE and E-mark compliance. Choose the isolated version where touch protection, interference suppression or positive grounding is required.
How much current can it supply?
It delivers 12 A continuously at a stabilised 13.6 V. For short power boosts it can provide up to 18 A for intervals of up to two minutes.
What input voltage does it need?
It runs from a nominal 24 V battery system and accepts an input range of 20 to 32 V DC, with a maximum of 35 V.
